Characterizing Students’ Thinking: Algebraic Inequalities And Equations, Kien H. Lim Nov 2006

Characterizing Students’ Thinking: Algebraic Inequalities And Equations, Kien H. Lim

Kien H Lim

This paper presents the findings of a study that explores the viability of using students’ act of anticipating as a means to characterize the way students think while solving problems in algebra. Two types of anticipating acts were identified: predicting a result and foreseeing an action. These acts were characterized using Harel’s framework, which involves the concepts of mental act, way of understanding, and way of thinking. Categories for characterizing acts of predicting and foreseeing were identified and developed based on thirteen 11th graders’ responses to problems involving algebraic inequalities and equations. The quality of students’ acts of predicting and …


Confronting Conventional Thinking: The Heuristics Problem In Feminist Legal Theory, Nancy Levit Jan 2006

Confronting Conventional Thinking: The Heuristics Problem In Feminist Legal Theory, Nancy Levit

Nancy Levit

The thesis of The Heuristics Problem is that the societal problems about which identity theorists are most concerned often spring from and are reinforced by thinking riddled with heuristic errors. This article first investigates the ways heuristic errors influence popular perceptions of feminist issues. Feminists and critical race theorists have explored the cognitive bias of stereotyping, but have not examined the ways probabilistic errors can have gendered consequences. Second, The Heuristics Problem traces some of the ways cognitive errors have influenced the development of laws relating to gender issues. It explores instances in judicial decisions in which courts commit heuristic …


Cognitive-Vestibular Interactions: A Review Of Patient Difficulties And Possible Mechanisms, Douglas A. Hanes, Gin Mccollum Jan 2006

Cognitive-Vestibular Interactions: A Review Of Patient Difficulties And Possible Mechanisms, Douglas A. Hanes, Gin Mccollum

Gin McCollum

Cognitive deficits such as poor concentration and short-term memory loss are known by clinicians to occur frequently among patients with vestibular abnormalities. Although direct scientific study of such deficits has been limited, several types of investigations do lend weight to the existence of vestibular-cognitive effects. In this article we review a wide range of studies indicating a vestibular influence on the ability to perform certain cognitive functions. In addition to tests of vestibular patient abilities, these studies include dual-task studies of cognitive and balance functions, studies of vestibular contribution to spatial perception and memory, and works demonstrating a vestibular influence …
